Police raided the Catonsville house looking for shooting suspect Rasheed Standford -- Barney's cousin -- but he wasn't home at the time.

Barney's half-brother, 25-year-old Tevon Smith, shot at Schneider after police gained entry into the house and were going room to room. Schneider and a second officer returned fire, fatally shooting Smith.

Following the raid, police found a .22-caliber gun in Barney's front pocket and he was arrested.
